IMPROVEMENT IN CAR-AXLE BOXES.

Specification forming part of Letters Patent No. 146,116, dated December 30, 187.3; application filed November 21, 1873.

To all whom it may concern:

Be it known that we, JOSEPH WHrTAKEn and SIMEON S. COOK, both of Woonsocket, in the county of Providence and State of Rhode Island, have invented a new and Improved Device for Preventing the Escape of Oil from Oar-Axle Boxes 5 and we do hereby declare the following to be a full and exact description of the same, reference being had to the accompanying drawing forming part of this specilication, in which- Figure l is a sectional View of a car-axle and box, to which our invention is applied; and Fig. 2, a perspective View of a portion of the axle, showing the washers.

Similar letters of reference in the accompanying drawing denote the same parts.

This invention has for its object to prevent the oil in a car-axle box from following the axle longitudinally, and thus escaping through the elongated orifice at the inner endof the box, through which the axle passes. To this end the invention consists in providing the axle with a bell-shaped or conical collar, 1ocated within the box between the bearingblock and the inner end, with its mouth toward the block, and a grooved disk or collar in the space between 4the flanges at the inner end of the box7 both acting to intercept the oiln as it works inwardly along the axle, and return it to the reservoir, as we will now proceed to describe.

In the drawing, A represents the box 5 B, the bearing-block, and (l the axle, all being of the usual form. On the axle O, between `the bearingblock and the inner end of the box, is a bell-shaped or liaring collar, D, closely fitting the axle and inclining toward the bearingblock, as shown in Fig. l. E represents a collar, having a grooved periphery located on the axle between the iianges F F at the inner end of the box.

Y There is always a tendency on the part of the oil in a car-axle box to work inward from the bearing-block along the axle and escape,

ter of the collar, from which it naturally falls back into the oil-reservoir. Any oil that is thrown against the inner or concave surface ofthe collar by the jolting of the ear, or from other causes, isl similarly guided and returned to the reservoir.

It will be seen, therefore, that the Acollar D guides all the oil that Strikes it directly from the axle to the reservoir. The grooved collar E performs a similar function for the oil that may be thrown against the axle inside the collar D, and throws it into the space between the anges F, which space communicates with the oil-reservoir through suitable orifices O.

The grooved periphery of the collar O prevents the oil from adhering, allows it to drop oft.` readily, and at the same time prevents the Oil A from passing to the inner side of the collar.

By this cheap and simple arrangement any escape of oil, from the cause above stated, is prevented.

The collars may be readily applied to any axle, and used in connection with any lubricating device or axle-box.

The collar D may be conical or bell-shaped,

as shown, and both collars should be so at-` tached to the axle as to be adjustable longii tudinally, or so that either may be removed,"`

at will.

We have shown the arrangement applied to` a car-axle, but 1t may obviously be used in` connection with shafting of any kind.

Having thusdescrlbed our invention, what we claim as new 1s- 1. The combination of a grooved disk or col` Y lar, E, with the journal C and car-box A, provided with the rear chamber between the flanges F F, said chamber having suitable openings, at or near its lowest point, communicating with the main body of the box, all substantially as described.

' 2. The combination` of a journal, a bell-1 shaped or conical collar,.and a grooved` disk or collar with an oil-reservoir beneath, substantially as described.
